An example of the behaviour of the algorithm in the Electrode Axis Estimation step. (a)This panel represents the result of the algorithm, i.e., the axis (r H,D ) and each axis point, A k , computed at each iteration, while the other three figures represent the steps executed at each iteration: (b) represent the computation of a point s, on the line connecting the two previous computed axis points, A k−1 and A k−2, with distance d from the point A k−1; (c) is the computation of a point q 0 that it is the point with the higher intensity value in “cubic” region R centered in s; (d) represent the computation of the axis point A k , i.e., the center of mass of a region R centered in q 0.
